    Size Chart Best Practices for Swimwear Shopify Stores

    Cup tops. Rise bottoms. Final-sale = sizing has to be right first time.

    Top Sizing

    Cup-based (32B, 34C, 36D) for fitted bikini tops. S/M/L for triangle / bandeau / sport tops. Show both systems if you sell mixed styles.

    Bottom Sizing

    Waist + rise. Low rise = on hips. Mid rise = at navel. High rise = above navel. Coverage notation: cheeky, full, modest. Customer picks both.

    Mix-and-Match

    Brands selling separates need: top chart, bottom chart, fit recommender that picks compatible sizes (e.g., size 8 cheeky bottom suggested with 32C top). Tailor Size Guide handles this with linked product chart configs.

    Final-Sale UX

    Make the size chart impossible to miss. Recommender mandatory before adding to cart (optional setting). Confirmation step at checkout: "These items are final sale. Size [M] confirmed?"
